Global Warming: More Men, Less Women?


We are hearing more and more about the effects of global warming, but recent research has shown that it can also directly influence human biology: it can change the ratio of son and child posterity.

A study has found that the warmer the average temperature, the more little boys are born: every 1 degree increase is 0.06% higher than the average, but it doesn't look any longer " can result every year. He has come to this conclusionSamuli Helle, a researcher at the University of Turku's School of Economics, studying the North Finnish numeral group, the Lappish group.

100 little girls, 105 little boys

Experts believe that the conception is the same, that is, 50-50 percent is not the proportion of the two, but not all fertilized oocytes become pregnant, and premature births are very common. "Overall, fewer babies are born than boys," he says Steven Orzack, a researcher at the Fresh Pond Research Institute in Massachusetts. This is due in part to the fact that girl fetuses already have their lower egg cells, and the potential for genetic incompatibilities that are not compatible with life is greater in these cases, and because of their potential in ovaries. Because genetically problematic embryos are more likely to die early in pregnancy, there is a greater chance of having a baby. On average, 100 girls per newborn will receive 103-106 newborns. At the same time, newborns are biologically "weaker", more susceptible to disease, and to early death. For this reason, however, the scientists have not yet been able to accurately determine.It changes the gender dimension of global warming
Fetuses and newborns are also more sensitive to environmental influences. Dr. Misao Fukuda Japanese research and its societies have studied the demographics of areas that have suffered some kind of severe natural disaster (especially earthquakes). Natural disasters are accompanied by extreme stress. 9 months after the disasters, the number of children born in these areas has fallen by 6 to 14 percent (compared to one year earlier). According to Dr. Fukuda, natural disasters related to global warming can have similar consequences.

Warmer weather - more little boys

Scientists, however, think that people will adapt quite quickly to this situation. In other words, it is possible that due to extreme weather and stress related to catastrophes, fewer children will be born temporarily, but in the long run, global warming may lead to an increase in the number of young children. It should also be borne in mind that natural disasters, such as forests and floods, only have a local effect.

Is this really blood for us?

According to professionals these research findings do not mean that women will "run out" of a few years. Helle believes that even though global warming may be a good factor that influences gender, further research is needed to unequivocally determine whether it is global or not. And Fukuda points out that any changes do not affect the different regions of the Earth in the same way.
"I also don't believe it is possible that these changes will last," adds Fukuda, whose research also found that the proportion of newborns was normalized in the short term: -50 percent should be the proportion of little boys and little girls. (Via) You may also be interested in:
